    • Abstract:
      Surface and borehole geophysical methods exist to measure in-situ properties and structural

      characteristics of earth materials. Application of such methods has demonstrated cost savings through

      reduced design uncertainty and lower investigation costs. Routine use of geophysical methods, however,

      remains limited due to the specialized nature of the work and limited industry experience with its

      application to real-world projects. In an attempt to address that issue, Caltrans staff submitted a proposal

      for research aimed at developing a reference document describing the quantitative measurements of

      material properties that may be obtained using geophysical methods. In support, Caltrans staff surveyed

      the available literature to evaluate: 1) the current state of the practice regarding the use of geophysics for

      transportation projects, 2) the body of available literature that documents the use of geophysical methods

      to derive engineering properties of soil and rock, and 3) any standardized or recommended methods and

      procedures.
